|Rick's rocker box is pretty close to completion. I just need|
to finish the ground board and bearing components.

|Rick's mirror is supported by a 6-point non-flotation|
mirror cell. Thicker mirrors take simple cells without
any problems. Oversize knobs make collimation easy.
|Note the Telrad is supported by two clamps. The other|
clamps are for the alt bearings and sliding counter weight.

|This Nova Optical Systems certified primary is a 10" F5|
now with a beautiful 2-speed 2" Moonlite focuser on
its heavy duty focuser bracket.
|The nice thing about these Destiny spiders is that they're|
collimatable with a spring-loaded center-stalk and
can be adjusted a big along the optical axis.

|A 12.5" kit for Rick in Silver City, New Mexico is underway. Here|
the OTA rings are close to completion. I need to add a mirror cell, mount
the spider and focuser bracket as yet. This kit will be complete,
including optics, focuser and spider.

Check out Jay's Astronomical blog at http://jaysastronomyobservingblog.blogspot.com/ The telescope, a 17.5" Dobstuff truss telescope was built for him in 2014. Jay lives in Herriman, Utah.

|Bruce 10" F6 with partially completed rocker box. I mount the telescope|
with all its accessories and check for balance and motion.
|As compared to the original Discovery -- this telescope is considerably lighter|
and easier to handle. The rocker box is much smaller as well.
|The top ring, Telrad and laser "finder". The "strings" are yet to be affixed|
to the telescope. Along with its longer focal -- the strings will add rigidity.

|Bruce's 10" F6 with the "mirror box" complete. Note the|
"hooks" -- for the strings to be added later.
|This telescope sports the "Easy Transport Telescope" option|
(ETT). The bottom half of the struts are in place.
|The "intermediate" ring re-introduces rigidity to the|
OTA. The struts are 1.25" black anodized 6061 aluminum.
|And, the "top half" of the struts in place.|

|The OTA is closer to completion. Here, the top ring with curved-vane spider|
and JMI focuser is in place.
|With the mirror cover removed, the Discovery mirror is clear visible on its|
original mirror cell. Note the Destiny spider is "collimatable" -- no need to
loosen 2 and tighten 1 collimation thumb-screw. It's spring loaded.
|With all the optical elements in place, I'm able to computer|
the strut length as 55 7/8". Now, with adjustable
struts -- I can test it under the stars and then
finish the OTA in a couple of days.
|A photo of a telescope similar to Bruce's -- AFTER reconstruction.|
|And "before" reconstruction. A huge difference in weight and size.|
